管道江底隧道穿越技术被广泛应用于管道施工建设中,而隧道受复杂江底地质情况、不均衡水压等诸多因素的影响易出现渗漏。管道江底隧道出现渗漏的原因主要有施工质量和自然条件两个方面。根据遵循国家法律法规、节省投资、整治后的隧道维检修方便等隧道整治原则,提出了充水、回填和止水等3种整治措施,并对各种措施从施工难易程度、整治效果和存在问题进行了详细分析,指出止水措施虽然一次性投资高,但可以从根本上恢复隧道原状,优于其他两种措施。
Pipeline crossing tunnel crossing technology is widely used in pipeline construction, and the tunnel by the complex conditions of the river bottom, uneven pressure and other factors prone to leakage. There are two main reasons for the seepage of the tunnel river tunnel: construction quality and natural conditions. According to the principle of following the laws and regulations of the state, saving investment and rehabilitating the maintenance of the tunnel, the three tunnel renovation measures, such as water filling, backfill and water stop, are put forward, and the measures of construction difficulty, remediation and The existing problems were analyzed in detail, pointing out that although the one-off investment in water-stop measures is high, it can fundamentally restore the original status of the tunnel and outperform the other two measures.
